Around the
pattern there is an inner frame of <i>0.3</i> times the width of one
square, which continues the checkered pattern. The pattern is completed by
a solid white outer frame of <i>0.7</i> times the width of one square.
In the
center of the pattern there are two circular marks, one black on a white
square and one white on a black square. The radius of both marks
correspond to one third of the side length of the respective enclosing
square.
These marks are used by <a href="gen_grid_rectification_map.html"><code><span data-if="hdevelop" style="display:inline">gen_grid_rectification_map</span><span data-if="c" style="display:none">gen_grid_rectification_map</span><span data-if="cpp" style="display:none">GenGridRectificationMap</span><span data-if="com" style="display:none">GenGridRectificationMap</span><span data-if="dotnet" style="display:none">GenGridRectificationMap</span><span data-if="python" style="display:none">gen_grid_rectification_map</span></code></a> to rotate the
detected layout of the grid points into the correct orientation. It is
assumed that the black mark is positioned to the left of the
white mark, when oriented correctly.
The file <a href="#GridFile"><i><code><span data-if="hdevelop" style="display:inline">GridFile</span><span data-if="c" style="display:none">GridFile</span><span data-if="cpp" style="display:none">GridFile</span><span data-if="com" style="display:none">GridFile</span><span data-if="dotnet" style="display:none">gridFile</span><span data-if="python" style="display:none">grid_file</span></code></i></a> contains the PostScript description of the
